GCSE-readyChanging UK cities: regeneration and sustainability
UK cities have boomed, declined and been reborn. Today the challenge is to build the homes people need while making cities greener.
How UK cities have changed
Suburbanisation: in the 1900s, with trains and cars, many moved to the suburbs on the edge of cities.
Deindustrialisation: from the 1960s to the 1980s many inner-city factories and docks closed, leaving unemployment and derelict land.
Counter-urbanisation: some people moved out to small towns and villages.
Re-urbanisation: since the 1990s, many city centres have grown again, with new flats and jobs.
Regeneration
London Docklands: after the docks closed, the area was rebuilt from the 1980s, including Canary Wharf, a major financial district.
Queen Elizabeth Olympic Park: land at Stratford in east London was cleaned up and rebuilt for the 2012 Olympic Games, then turned into homes, parks, sports venues and a university and cultural quarter.
New building can use brownfield sites (land built on before) or greenfield sites (never built on). Many cities are surrounded by a protected green belt.
| Brownfield | Greenfield | |
|---|---|---|
| Advantages | Reuses land; services already nearby; protects countryside | Cheaper and easier to build on; pleasant setting |
| Disadvantages | May need expensive clean-up of pollution | Loses countryside and habitats; more car journeys |
Sustainable cities
Features: good public transport and cycle lanes; green spaces and trees; energy-efficient homes with solar panels; recycling; and homes built near jobs and services.
Example: BedZED (Beddington Zero Energy Development) in Sutton, south London, completed in 2002, was designed with thick insulation, solar panels and a car club to cut energy use.
A council must choose between building 500 homes on a brownfield site in the city or a greenfield site outside it. Give one reason for each choice.
- Brownfield: it reuses old land, protects the countryside, and residents are close to jobs and public transport.
- Greenfield: it is often cheaper and quicker, as there is no pollution to clean up.
- The best choice depends on cost, the environment and how people will travel.
Answer: Brownfield protects countryside and is near services; greenfield is often cheaper and easier.
UK cities went through urbanisation, suburbanisation, deindustrialisation, counter-urbanisation and re-urbanisation. Regeneration rebuilds run-down areas, as at London Docklands and the 2012 Olympic Park in Stratford. Brownfield sites reuse land; greenfield sites are cheaper but lose countryside. Sustainable cities use public transport, green space and efficient homes, like BedZED.
- Urbanisation
- An increase in the share of people living in towns and cities.
- Sustainable
- Meeting the needs of people today without harming the ability of future generations to meet theirs.
- Development
- Improving people's quality of life, through wealth, health, education and freedom.
- Not “Farmland that has never been built on”. That is greenfield.
- Not “People moving into city centres”. That is re-urbanisation.
